VOIP Call disconnection Problem

Dear All,

We have a 64KB lease line from head office to regional office.

VOIP is implemented between both the locations using VIC-2FXS voice cards.

Cisco 1750-V router is used at the Head office and 3com pathbuilder router is used at the regional office.

When I make a voice call from Head office to regional office call lasts as long as we don’t disconnect it manually.

But when we originate a voice call from cisco router to 3com router call establishes successfully but lasts only for 10 to 15 seconds and disconnects while we are under conversation.

Basically we have a call disconnection problem from one end.

Any workaround to solve the problem will be appreciated


Re: VOIP Call disconnection Problem

Please post the following

sh run

sh call active voice brief, when the call is active on the router.

Following debugs of the call so we can see the disconnection
